in D+O, people use isDefinedBy  primarily in their data documents 
(i.e. the ontology instance stuff)where it provides a useful function 
(there's not always a direct namespace link to the class definition 
in one step)  - why would you leave it out?  seeAlso seems irrelevant 
to Owl, but seems like there is no trouble having it in the 
annotations (i.e. no worse than someone adding their own creation) - 
any particular reason to leave these two out, other than general 
principles (i.e. do they actually break anything, as opposed to 
offending ones sensibilities?)
